An = -4 + (n - 1)(7)
This being in the form of the explicit rule for an arithmetic sequence you can pick out the d and a1.
an = a1 + (n - 1)(d)
d = 7
a1 = -4
Answer:
30⁰ , 60⁰ , 90⁰
Step-by-step explanation:
Let the angles x , 2x , 3x
By angle sum property:
x + 2x + 3x = 180⁰
6x = 180⁰
x = 30⁰
Angles are : 30⁰ , 60⁰ , 90⁰
24,000,000 because 600,000 is more than 1/2 1,000,000 so you round up.
Answer:
c is parallel to d
Step-by-step explanation:
the degrees need to be equal in order for them to not intersect at any point, if you set x = 10 as given.
